T0 all whom, t may concern,.-

Be it known that I, PHILIP FLEMING, a

citizen of the United States, and a resident of i Burton View, in the county of Logan and State of Illinois, have invented certain new and useful Improvements in Riding-Harrows, of which the following is a specification.

My invention is an improvement in ridingharrows 5 and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.

Referring to the drawings forming a part hereof, Figure 1 is a plan view of my irnproved riding-harrow. Fig. 2 is a rear elevation. Fig. 3 is a section on the line 3 3 of Fig. 1, and Fig. 4 is a section on the line 4; l of the same figure.

In the practical application of my invention I provide a frame comprising the longitudinal bars a, connected at their ends by the cross-bars a. Downwardly-projecting arched brackets c2 are connected with the lower faces of the longitudinal bars, the brackets being provided with bearings a3 for the reception of a main shaft at, having a cranked portion ai within the bearings and upon its ends without the bearings the supporting-wheels c6.

A harrow-section B is supported below the frame by the main shaft. The section B comprises a plurality of parallel longitudinal plates 6, spaced apart from each other and provided with a plurality of spaced perforations 6, the perforations of each plate being in alinement with the perforations of the other plates. A series of rods 61 traverse the openings in the plates, the outer rods of the series being provided with collars 63 61 upon either side of the outer plates for retaining the plates in position with respect to the rods.

Each of the rods 62 is provided with a series of harrow-teeth 65, the teeth upon the alternate rods being staggered with respect to the teeth upon the intermediate rods. Upwardly-projecting arms 6, rigid with the rods, are arranged adjacent to the central plate, and the arms are connected together by a bar 67, the arms upon the alternate rods being arranged upon opposite sides of the bar. A lever 68, integral with one of the arms, is provided with a catch 69 for engaging a perforated quadrant 610 upon the bar, the catch being normally maintained in engagement with the quadrant by a spring 611. Upwardly-projecting arched brackets 612 are connected with the rods, the upper surface of the brackets being provided with bearings 613 for engaging the cranked portion of the shaft a4. The ends of the brackets 612 are provided with openings for receiving the rods and are arranged adjacent to the outer plates, being retained in their proper position by the collars 61 upon the front rod and by collars 611 upon the intermediate rod. Rings 615, having eyes 616, are arranged upon thefront rod adjacent to the collars 63, and cables or chains C connect with the eyes 61G and extend upwardly over pulleys c, journaled in the frame, to arms c-, secured to the shaft' c1, j ournaled in bearings c3 upon the upper face of the longitudinal bars of the frame. The arms c are arranged in oppositely-disposed pairs, the upwardly-projecting pair for receiving the cables attached to the front rods and the downwardly-projecting pair for receiving the cables attached to the rear rods. A lever c5 is secured to the shaft c2, the lever being provided with a catch c, normally retained in engagement with the quadrant c7 by means of a spring cs. When the shaft c2 is rotated to the rear by the lever c5, the movement of the arms elevates the harrow by means of the ilexible connection of the arms therewith.

Lateral harrow-sections D D are arranged upon either side of the central section B and are connected thereto by a universal joint d between the outer rods of the side sections and the outer rod of the central section. The lateral sections D D are similar in all respects to the central section, comprising the longitudinal parallel plates d', provided with the spaced openings d2 and the rods d3, traversing the openings and provided with teeth d1. A similar means is provided for varying the inclination of the teeth with respect to the sections comprising the upwardly-projecting arms d5, connected together by a bar d, a lever 67, integral with one of the arms, being provided for manipulating the bar. The lever dl is provided with a catch d8,normally pressed TOO into engagement with perforations in a quad- IOS IIO

At the rear of the frame the hooks ai are arranged to engage the perforations in the quadrants d in the toothed quadrants on the side sections.

A seat E is arranged upon a cross-plate e, the plate being provided at either end with pins e for engaging a series of perforations e2 in the longitudinal bars of the main frame,

By engaging the pins in different holes of the series the seat may be moved backward or forward on the bars for the purpose of adjusting it with respect thereto. The side plates of the central section are provided with brackets (LX, having transversely thereof a series of perforations 0,0 for engagement by the hooks j' of the doubletrees F.

The doubletrees F are composed of a plate f', having slidably mounted upon either end thereof relatively short plates f2, the relatively short plates being provided with hooks f3 for engagement by the chains f4 upon the inner plate of the side harrow. By this arrangement the draft upon the machine is equalized, and it may be still further distributed by extending the sliding bars f2 and connecting the hooks with the outer plate of the lateral harrows. The sliding plates are held in their adjusted position by means of pins f 5 engaging alined perforationsfG in the lates.

p In operation the central and side harrows would be lowered into contact with the ground and the teeth adjusted at a suitable inclination with respect to the harrows. In moving the machine from place to place the outer end of the side harrows would be elevated and engaged with the hooks on the frame and the central harrow would be elevated out of contact with the ground, thus leaving all parts free from the ground except the wheels. If desired, a tongue may be secured directlyto the frame, and for this purpose I provide brackets al upon the front of the machine. Rods f7, provided at their outer ends with chains f8 for engaging eyes f upon the relatively short plates, are provided for limiting the outward movement of the short plates, the rods being attached at their inner ends to the tongue.

If desired, coil-springs may be arranged on the pivot-pin of the tongue, on either side thereof and between the tongue and the lugs uw. This arrangement reduces the strain of turning somewhat.

Having thus described my invention, what I claim as new, and desire to protect by Letters Patent, is-

l. In a riding-harrow and in combination, a

'harrow-sections, bearings on the brackets for engaging the cranked portion of the main shaft, a shaft journaled on the main frame above the main shaft, oppositelyprojecting arms on the shaft within the frame, pulleys journaled at the corners of the frame, eyes on the corners of the harrow-sections, flexible connections between the eyes and the oppositely-projecting arms and engaging the pulleys, a lever secured to the shaft, a toothed quadrant on the frame, a spring-actuated catch on the lever for engaging the teeth of the quadrant, and harrow-sections arranged upon either side of the central section and movably'connected thereto.

2. In a riding-harrow and in combination, a main frame, brackets extending below the frame, a shaft journaled in the brackets and having a cranked portion, wheels on the ends of the shaft, a harrow-section below the frame, bearings on the harrow-section for engaging the cranked portions of the shaft, a shaft journaled in the frame, oppositely-arranged pairs of arms on the shaft, means for rotating the shaft, and a flexible connection between the arms and the harrow-section.

3. In a riding-harrow and in combination, a frame, a shaft journaled on the frame and having a cranked portion, wheels on the ends of the shaft, a harrow-section supported by the cranked portion, a second shaft journaled on the frame and provided with oppositely-arranged pairs of arms, a flexible Vconnection between the arms and the harrowsection, and means whereby to rotate the second shaft.

4. In a riding-harrow, the combination with the frame having depending brackets, of a shaft journaled in the brackets and having a cranked portion, wheels on the ends of the shaft, a harrow-section having brackets provided with bearings for engaging the cranked portion of the shaft, and means on the frame for elevating and depressing the harrow-section.
